Treatment time: 1 ÷ 3 minutes
Usage temperature: 40 ÷ 60 ° C
Concentration: 10 ÷ 20 g / l
Bath score: 7.2 ÷ 14.4 points of total acidity
pH of the bath at 20 ° C: 4.5 ÷ 5.5

Control of bathing

Take 20 ml of sample, add 4-5 drops of phenolphthalein indicator and titrate with a 0.1 N sodium hydrate solution until a constant pink color.
The number of ml of 0.1 N sodium hydrate used represents the bath score which, for a 10 g / l preparation, must be equal to about 7.2.

Alimentation

For each point consumed, add 1.4 kg of FIPROPHOS 540 per 1000 l of bath.

Storage

Store the product in its original packaging, in a cool and dry place, protect from frost.
